DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] It should be noted that the terms up, down, left, right, inside, outside, first, second, etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features, unless otherwise clearly and specifically defined.

[0029] See also Figures 1 to 5 As shown, the present invention discloses a cable corrugated paper feeding device having a tower-shaped base 1. A fixing hole 2 is provided at the bottom of the tower-shaped base 1, and the fixing hole 2 is used to fix the entire device on a frame for use with high-voltage twisting equipment. Three annular adjustment grooves 3, 5, and 7 are formed on the tower surface of the tower-shaped base 1, and three adjustment blocks 4, 6, and 8 are respectively installed on the three adjustment grooves 3, 5, and 7. The number of adjustment grooves and the number of adjustment blocks are not limited by the drawings and embodiments, and can be determined according to design requirements and actual needs. The adjustment blocks 4, 6, and 8 can slide on the corresponding adjustment grooves 3, 5, and 7 to realize the adjustment function. After being adjusted into place, the adjustment blocks 4, 6, and 8 can be secured with the aid of a fixing member 10 (bolts are shown in the figure, and only shown for ease of understanding). Figure 2 and Figure 3 The adjusting blocks 4, 6 and 8 are provided with paper guide holes 9 for the crepe paper to pass through.

[0030] The optimized design of the present invention is that the paper guide hole 9 is an arc-shaped hole with both ends tilted outward, so that the crepe paper can be bent after passing through the paper guide hole 9, so as to better wrap each conductor later. Moreover, the width of the paper guide hole 9 of the adjustment blocks 4, 6, and 8 on the three adjustment slots 3, 5, and 7 gradually narrows from the bottom to the top of the tower-shaped base 1, and further when the crepe paper passes through at least two paper guide holes 9 from the bottom to the top of the tower-shaped base 1, the crepe paper is gradually bent, avoiding excessive bending at one time and causing the tape to break, and is also more conducive to the crepe paper wrapping each conductor.

[0031] In order to better position the adjusting blocks 4, 6, 8, positioning notches 11 are formed on both sides of the adjusting blocks 4, 6, 8 corresponding to the adjusting grooves 3, 5, 7, and the fixing parts 10 are stuck in the positioning notches 11, so that the adjusting blocks 4, 6, 8 can be multi-dimensionally positioned to avoid displacement and deflection of the adjusting blocks 4, 6, 8, thereby ensuring stable performance and the quality of the twisted wire core products.

[0032] In order to improve the roundness of the twisted wire core, a filling rope passing hole 12 is opened on the bottom surface of the tower base 1, and a filling rope through hole 13 is opened on the top of the tower base 1. The filling rope passes through the filling rope through hole 12 and the filling rope through hole 13 to fill the gap between the conductors of the twisted wire core, thereby improving the roundness after twisting.

[0033] The bottom of the tower base 1 of the present invention is also concave to form a plurality of hollow holes 14 (5 hollow holes 14 are shown in the figure), and the plurality of hollow holes 14 are evenly distributed. The hollow holes 14 are preferably designed to be in the shape of a bullet head. This design can reduce the weight of the device, save manufacturing costs, and further ensure stable performance, safety performance and good mechanical properties.

[0034] The present invention further designs the tower base 1 to be conical, which has a more stable structure. The fixing holes 2 and the filling rope threading holes 12 are arranged on the bottom surface of the cone, and the filling rope through holes 13 are arranged on the top of the cone.

[0035] The present invention is installed on a frame through the bottom of a tower-shaped base 1, and is used in conjunction with a high-voltage twisting device. Before the present invention is started, the crepe paper is passed through the paper guide holes 9 of the adjustment blocks 4, 6, and 8 on the corresponding adjustment slots 3, 5, and 7, and the first rough adjustment can be performed through the fixed hole position 2, and then the second fine adjustment is performed by sliding the adjustment block 4, 6 or 8 through which the crepe paper passes, so that the crepe paper can be adjusted to a suitable guide angle and a precise wrapping degree. This device can not only adjust the guide of the crepe paper, but also adjust the wrapping degree of the crepe paper. In particular, the use of three adjustment slots can more accurately adjust the guide of the crepe paper, and the wrapping angle of the crepe paper can be adjusted by three groups of adjustment blocks, so that the wrapping degree of each strand of the split conductor twisted cable core meets the production process requirements.

[0036] In actual use, when the conductor strands are cut and twisted into cores in high-voltage cable production, the conductor strands pass through the tower surface of the tower base 1, and the crepe paper is guided through the paper guide holes 9, fed and then fully wrapped around each conductor strand. The present invention provides crepe paper with a suitable angle to ensure the quality of the twisted core products and accurate surface roundness.

[0037] In summary, the key technology of the device of the present invention is that when the high-voltage cable is produced and the conductor is split and twisted into a core, the crepe paper fully wraps each strand of conductor. The cable crepe paper feeding device according to the present invention is proposed, designed and modified on the basis of the original high-voltage cable production equipment to improve the guiding accuracy of the crepe paper and the wrapping degree of the crepe paper of the strand. In addition to retaining the original production function, the equipment adds 1-3 adjustment blocks, 1-3 adjustment slots and other accessories, thereby improving the quality of the high-voltage cable product's split conductor twisted core and improving the product qualification rate.

[0038] The above description is only an implementation example of the present invention and is not intended to limit the protection scope of the present invention. It should be noted that equivalent changes made by those skilled in the art based on the design ideas of this case after reading this specification shall all fall within the protection scope of this case.
